The reader of RTP is granted just a few paragraphs before habit is introduced: Habit! That able but slow-moving arranger who begins by letting our minds sufer for weeks on end in temporary quarters, but whom our mind is nonetheless only too happy to fnd, for without it, reduced to its own devices, it would be powerless to make any room habitable. (SW, 9, translation altered; I 8) Implied is a view of mind: powerless to interfere with habit’s course, but (...) equally powerless to reconcile us even to something as innocuous as a room, were it not for habit’s work. Corresponding to this is a view of the world: hostile. The objects are nasty, imposing, menacing: a ‘mentally poisoning’ smell, malicious curtains and a cruel mirror (SW, 9; I 8). Habit, unbidden but welcome, steps in. The mirror becomes compassionate. Habit is a central aspect of the narrator’s worldview. It appears both at major plot points and in signifcant theoretical passages. Proust had already thematised habit in some of his earliest published work – notably in ‘Violante ou la Mondanité’ (1892) (‘Violante, or High Society’) – as well as in unpublished material (see II 1352 fn. 2). His ideas have their roots in his philosophical education, where habit formed a key part of the syllabus. Indeed, in retrospect, we can say that Proust may have been taught philosophy at a time and place where habit, as a philosophical topic, was approaching its high watermark, as a major theme in French philosophical thought. Another major theme, of course, was time. (shrink)

Leibniz’s short letter to the mathematician and physicist Ludovico Casati of 1689 is a short but interesting text on the Principle of Identity of Indiscernibles, to which it is entirely dedicated. Since there is no watermark in the paper of the letter, the letter is difficult to date, but it is likely that it was written during Leibniz’s stay in Rome, sometime between April and November of 1689 (A 2 2 287–8). When addressing the letter, Leibniz wrote ‘Casani’, but (...) this seems to be a mistake and the real addressee is thought to be Ludovico Casati, nephew of Paolo Casati, the Jesuit mathematician. The letter, reproduced in the Berlin’s Academy edition of Leibniz’s works, was first published by Gerhardt in the Archiv für Geschichte der Philosophie in 1892 (Gerhardt 1892: 53–54). It also appears in Robinet’s Iter Italicum (Robinet 1988: 134–35). But neither Gerhardt nor Robinet provide a philosophical discussion of the letter, and I am not aware of any other philosophical discussion of it. Furthermore, as far as I know, the letter has never been translated into any language. Thus I shall here provide a transcription (from A 2 2 288–89) and a translation of the letter into English, and a philosophical discussion of its treatment of the Identity of Indiscernibles.

How comes that two organisms can interact with each other or that we can comprehend what the other experiences? The theories of embodiment, intersubjectivity or empathy have repeatedly taken as their starting point an individualistic assumption (the comprehension of the other comes after the self-comprehension) or a cognitivist one (the affective dimension follows the cognitive process). The thesis of this book is that there are no two isolated entities at the origin which successively interact with each other. There is, rather, (...) an impersonal stratum – the original affectivity (Gefühlsdrang) – which lets the living organisms be constitutively attuned with the expressive dimension of the life from the very beginning. The book aims to rethink the issue of corporality on the basis of a biosemiotics of the interaction between lived body (Leib) and environment (Umwelt). The human emotions reveals themselves as devices that experiment further attunement levels and expose the human being – because of her ex-centricity – to the alienation in various forms of the psychopathological existence. This is an unprecedented perspective that turns to psychopathology to reread against the light the watermark weaving the structure of personal singularity. What emerges is an intermediate territory confining both with philosophy and psychiatry: the psychopathology of ordo amoris. The author advances the project of a new psychopathology of ordo amoris, not only tackling with the 19th-century tradition of psychiatry and phenomenological psychopathology, but also with the contemporary disputes on intersubjectivity in phenomenology and with those on schizophrenia as disruption of aida or as disembodiment process in psychiatry. What results from his project is the first systematic study on the international level showing the relevance of Schelerian concepts of body schema (Leibschema) and order of feeling (ordo amoris) to understand the disruptions of emotional regulation on the psychopathological dimension as well as on the formation process of the singularity.

This work focuses on enhancing security for transmitted e-documents, such as e-stamp papers, within wireless environments through dynamic authentication using variable circular concealment of multiple invisible signature images. This method is driven by encrypted secret keys and session-based random numbers, alongside a region-specific bit casting strategy and dynamic bit sequencing for multiple signatures to bolster security and robustness. Multi-copy signature marking on non-overlapping document areas, coupled with varied bit encoding strategies for each modified pixel byte coefficient in cover image sub-blocks, (...) further enhances protection and resilience against attacks. The reverse transformation of bit-coded pixel byte components in spatial domain ranges is preserved, allowing threshold-based bit creation to perform effectively even under attack scenarios. With secret information and random numbers transmitted to the receiver, the securely embedded signature bits can be reliably identified in their original sequence from the forward-transformed sub-block pixel elements. Experimental results validate that this approach significantly improves authentication and confidentiality, surpassing prior methods in terms of security and reliability. (shrink)
